TYPEWRITER ACCESSORY.

Application filed March a, 1925 Serial No. 13,812.

v The object of this invention is to provide certain convenientfeaturesin the form of accessoriesto be used jointly or separately inconnection with a typewriter, and consisting of a casing or hood forcovering and protecting the machine and for deadening its sound, anerasingtable provided with means for gauging the correct position of thelast printed line upon the paper, and a movable copyholder located abovethe typewriter and situated directly in the vision of the operator whensitting in a normal, upright position.

With this and other objects in view the invention consists in certainconstructions, improvements and combinations as will hereinafter befully described and specifically pointed out in the claims hereuntoappended. While this-invention may be modified to suit different stylesof typewriters it is particularly applicable to a power typewriter, inwhich the motions of the carriage are under key-control, and in theaccompanying drawings the invention is shown adapted for use inconnection with the machine illustrated and described in my applicationfor power typewriters, Ser. No. 13,613 bearing even date with thisapplication.

In the accompanying drawing, Fig. 1 is a sectional side-elevation of thecasing and other accessories, Fig. 2 is a partial end-view of the same,and Fig. 3 is an enlarged View showing the manner of locating the casingin relation to the typewriter by means of handles.

Referringto Fig. l, A is an outline of the power typewriter alreadyreferred to, and whicheXcept for the keyboardis completely covered bythe casing B. This casing may be constructed of any suitable material,and its top is provided with two doors C and D, between which is anarrow aperture for the printed portion of the paper to exit by. Thefront door C is hinged at C and when opened assumes the positionindicated by dotted lines. This door is provided with a glass plate inorder to make the writing visible when the door is closed. The object ofthis door is largely to give the operator access to the machine whencertain adjustments are required, for as will be shown hereinafterprovisions are made for doing most of the erasing above the glass door.The rear door D is hinged at D and is provided with an inclined table E,for the printed paper to rest against after it has been fed out throughthe aperture, and rises above the top of the casing. Other objects ofthisinclined table Wlll be referred to hereinafter. In front of theinclined platform and directlyin the vis1on of the operator when sittingin a normal uprlglit position, is mounted the copyholder Thiscopyholder, which is made in; the

shape of an open frame, is connected. to each of the two ends of theinclined table by movable links F and F which permits the copyholder toassume two distinct positions of rest. Its normal working position isshown in Fig. 2, where the links are resting on the top of the buttons F3 and F while the obect of the second position, shown in Fig. 1, wherethe links rest against the other of buttons F ,isto enable the operatorto readily examine that portion of the writing that is resting on theinclined table.

In order to locate the casing properly in relation to the typewriter, soas to make the paper pass out through the aperture in the top of thecasing, I employ two handlesG, attached to the typewriter through a pairof openings, in the form of round holes B and B situated one at each endof the easmg. The handle at the left hand end (F ijg. 8) is attached tothe squared end of the paper-feed rod 260, situated directly beyond thehandle 210, as shown i i-Fig. 5 of my companion application alreadyreferred to. This handle is made to work loosely in the correspondingopening B of the casing, and enables the operator to feed the paperup'and down by hand from outside the casing. This makes it possible tobring the writing quickly above the glass door to makeany necessarycorrections on the table E, and to return the paper to the printing linewithout opening the front door. Only in case of corrections on the lastfew lines of the paper will it be necessary to open the front door. Thismanner of erasing has the additional advantage of keeping the erasuredust away from the machine. The other handle issimilarlyattached-through the opening B in the opposite end of thecasing-to the squared end of the winged rod 207. This rod, as shown inFigs. 6 and 7 of my companion application, releases the paper in the"carriage, and makes this operation possible from outside the casing.While my preferred construction shows these locating handles operatingthe paper line feed and the paper release mechanism, I do not wish toconfine myself to this particular use of such handles, as a differenttypewriter construction might make other uses for them more desirable.

In order to make the table E rigid to work against, the rear door D isheld in locked position when closed, by means of a springactuated pawlK, fastened to the left hand end of the door. This pawl grips a hook J,fastened to the top of the casing B. WVhen opening this rear door theoperator grips the .forwardly extending portion of the pawl K,

and by lifting it releases the pawl from the hook J, and forces thelower rear part of the pawl against an abutment J This transorms t epawl into a handle for opening the door, which when opened assumes theposition indicated by dotted lines in Fig. 1. It is in this openposition that the paper is inserted. As soon as a new sheet has beengripped by the feed rolls, the loose end of the sheet is pushed back inbetween the machine and the rear wall of the casing, after which thedoor is closed again.

Another object of the table E is to utilize it as a means for gaugingthe correct position of the last printed line upon the paper, so as toenable the operator to provide for the proper margin at the bottom ofthe page. For as it is obviously dil'ficult to determine the position bythe bottom of the sheet itself, which is usually hidden behind the feedrolls, I propose to determine this position by the top of the sheet, asit reaches the top edge of the inclined platform or table. In additionto this, one or several scored lines upon the face of the table, asindicated at E may be employed for gauging different length of sheets.

It should be understood that a table and a copyholder, such as has beenhere described, and supported on movable hinges, that makes it possiblefor them to be rigidly held in their working positions and readily movedout of the way, may be utilized to advantage without the use of acasing. This may be done by substituting for the casing an appropriatesupport for the said hinges, or simply by removing the front portion ofthe casing as indicated by the broken lines 00-00 on Fig. 2.

Having thus fully described my invention, what I claim as new and usefulis- 1.
